SPlNNiNG-FRAME.

EPECIPICATION forming part of Letters Patent No. 318,936, dated May 26, 1885.

Application filed June 7, 18:4. (No model.) Patented in England August 20, 1584, No. 11,482.

To all whom it may concern.-

Be it known that I, Bonner WRIGHna subject of the Queen of Great Britain, and a resident of Philadelphia, Pennsylvania, have invented a new and useful Improvement; in Spinning-Frames, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part hereof.

Heretofore,in devices of this class, long sleeves surrounding the spindles for carrying the bobbins have been employed, and these sleeves have been provided with feathers to drive the bobbins; but in these cases the sleeves were of such great length as to create great friction upon the spindle and require frequent lubrication. The old sleeves were enveloped by and remained in contact with the whole bore of the bobbin during the entire upward and downward traverse of the latter. here such long sleeves are used it is necessary to stop the machine and remove the caps of the spindles in order to lubricate the sleeves.

The object of my invention is to obviate these defects; and to this end it consists in the combination of a bobbin having an internallygrooved bore contracted at its upper end to embrace the spindle abovethe carryingsleeve, the sleeve extending only partially through said bobbin and being provided with a feather for engaging with a groove in the interior of the bobbin,all as will be hereinafter described.

In the drawings, Figure l is an elevation of a spindle, showing the loose envelopingsleeve and its base or whirl, there being two feathers upon the sleeve; Fig. 2, a horizontal cross-section of the spool in place upon the sleeve and of the spindle, and a plan view of the top of the enveloping-sleeve and the lower flange of the spool. This section is upon the line V \V of Fig. 3; Fig. 3, an elevation of the spindle and a vertical sectional view of the spool, loose sleeve, whirl, lifting-rail,and baserail. Fig. at is aview in elevation of a broken section of the spindle, and a longitudinal sectional view of the broken-off upper parts of the spool and the sleeve upon the line X Y of Fig. 3, to show that the bore of the spool is larger in that part which surrounds the sleeve than in its continuation above the sleeve where it surrounds and comes into contact with the spindle A. The sleeve projects in an upward direction only part way through the bobbin.

A is the spindle, the base of which rests below in the spindle-rail of the spinning or twisting frame when in use. 0 is a loose sleeve surrounding the lower part of thespindle; C, the whirl of the sleeve 0. E E are two feathers or splines upon two opposite sides of sleeve 0. D D are the upper and lower flanges of the spool D. F F are two longitudinal grooves in the opposite sides of the bore or interior of spool D, which terminate above before reaching the upper extremity of the bore, thusleaving the bore of the spool intactfor a short distance above the upper end of the sleeve, (see G G, Fig. 3,) and permitting that portion. of the bore to fit the spindle snugly. These grooves, without detriment to the operation of my device, may be continued up through the whole length of the bore of the spool,as they remove but a comparatively small portion of the interior of the bore, as will be seen in Fig. 2 in cross-section.

Instead'of the sleeve 0 extending entirely through the bobbimit terminates a short distance below the top of the bore thereof, whereby, during the revolution of the sleeve, the bobbin in its upward traverse never entirely leaves it, but always remains in contact therewith,andis turned by the feather thereon. The contracted neck of the bobbin above the upper terminus of the sleeve clasps the spindle upon which the sleeve revolves,and is guided and steadied in its upward and downward traverse by the said spindle. The bore of the bobbin, at its upper end, is so much smaller than that portion of it surrounding the tube or sleeve 0 as to enable it to fit the spindle about as closely as the larger part of its bore fits the sleeve. When the bobbin is at its lowest point of traverse, thenarrow neck formed by the upper contraction of the bore will rest or nearly rest upon the upper end of the sleeve.

In the drawings, I have represented the feathers E E as being very short. They may be elongated down toward the base of sleeve 0 as far as is desired. Though I have shown two of these feathers, one may be dispensed with, and one groove be used. I prefer twofeathers and two grooves, however, as I find that a more even revolution of the spool is thus ohtained- The sleeve G when in'place'on the frame is revolved by a band or cord, which passes around the neck of the whirl O. The sleeve 0 turns freely upon the spindle A. H is the lifter-rail, through which the spindles and the sleeves 0 project, (see Fig; 3,) and I is a rail, upon which all the whirls O of the sleeve 0 rest. The spindles rest below in the ordinary rail.

The operation of my device is as follows: As the spinning progresses, the lifting-rail H rises and falls, slowly raising the bobbin in its upward motion and allowing it to drop of its own weight in the downward movement of the rail. As the bobbin D rises and falls, it traverses by its internal grooves upon the feathers E E, the upper terminus of the sleeve 0 being below the above-described contracted neck of the bobbin, but such sleeve being of such length that in the traverse of the bobbin the grooves of thelatter never entirely leave the feathers of the former, whereby the bobbin is continuously revolved by the revolution of the sleeve. The whirl'G sets upon the stationary rail I, as shown in Fig. 3, and be heath the lifting-rail H. The cord or band,

. therefore, which passes around the whirl 0 and turns the latter will always remain at one tension, because theposition of the whirl is not changed in the operation of spinning or twisting. It will be noticed that by my construction'the area of internal contact of the sleeve with the spindle is diminished,thus

moval of the cap over the spindle and the stoppage of the machine in order to lubricate the spindle. In my device the sleeve is so short, not extending through the bobbin, that I avoid all this difficulty and produce a simpler and more efficient device.

WVhat I claim as new is- 1. A bobbin or spool, D, provided with the internal groove,F, adapted to receive a feather, as describechin combination with the feathered sleeve 0 and spindle A, the bore of the said bobbin being of enlarged diameter to clasp the sleeve, and contracted above the sleeve to clasp the spindle, substantially as described.

2. The combination of a spindle, A, provided with a loose sleeve, 0, which is provided with a feather, E, and a spool 0r bobbin, D, having a groove, F, adapted to engage with said feather E, thelower part ofthe bore of said bobbin fitting snugly around said sleeve, and the upper part of the bore being smaller, as at G G, and fitting snugly around the spindle A'above the upper end of sleeve 0 when in place, substantially as described.
